GGD was founded as a local, family-owned business in 1988 by Peter Giglio, Sr. as a solo Technician out of his home. We grew. Providing superior customer service with values of Honesty & Integrity, our dedicated, experienced crews began additional service for Fairfax County homes in 1991. As our reputation for dependability spread, our 10 trucks & 15 employees outgrew the original Gaithersburg location in 2019 as we moved to a more spacious Rockville location. Peter’s son, Pete Giglio, Jr., succeeding his Dad, and long-time Operations Manager, Ryan Smart continue today to guide Gaithersburg & Fairfax Garage Door to satisfy the needs of DMV homeowners.

"Everything went fantastic Anthony was my technician, he was courteous, performed the job efficiently, did a great cleanup job of any materials in my garage. Explained exactly what was done and the future work that I needed to be done! I requested him to do the follow up work! The company itself is also great. They did follow ups via text and email; responded to everything quickly and were able to accommodate my schedule. I will continue to use them as a company."

Locksmiths questions, answered by experts

Keyless locks are often considered safer since they’re protected by passcodes instead of a physical key, making it harder to be picked. However, they are not infallible. And like all electronic devices, outdated models are more prone to problems and safety concerns. If you’ve experienced multiple lockouts in the past year, or your lock is responding slower than usual after you key in the passcode, it might be time to upgrade to a newer one. Even if your lock is working fine, you should still change your access code at least twice a year.

Lock bumping is a technique locksmiths use to quickly and quietly open a pin tumbler lock, typically found in most types of deadbolts. It involves inserting a specially crafted key, or bump key, into the lock and tapping or "bumping" it with a mallet or similar tool. The force applied causes the lock's pins to jump momentarily, allowing the lock to be turned and opened. Unfortunately, thieves also use this technique to break into homes. Luckily, products like a deadbolt strap will fortify your lock.

Rekeying should be done when employees leave or keys are lost, while replacement may be necessary for outdated or damaged locks.

Begin by checking the power source, typically a battery or wired connection. Ensure the battery is installed correctly, has sufficient charge, and isn't corroded. If it's a wired lock, examine the electrical connections to confirm they are secure and free from damage. Additionally, inspect the lock's programming or settings. Confirm that user codes or access credentials are programmed correctly and that any remote control devices are paired and functional.

Aside from the labor costs, several other factors can impact the cost of hiring a locksmith. If you can avoid services during off-hours, you can save on fees often charged for urgent requests. Consider additional factors such as:

  • Type of services required

  • Emergency call fees

  • Home and lock location

  • Number of locks to repair or install

  • Peak hours

  • Type of locks
